• What is the cause and solution for SAP error message R8402 - You are not authorized to perform this action with DataSource &1 ?

  The SAP error message R8402 indicates that a user does not have the necessary authorization to perform an action related to a specific DataSource. This error typically occurs in the context of SAP BW (Business Warehouse) or SAP Data Services when a user attempts to access or manipulate data from a DataSource for which they lack the required permissions.
  Cause:
  
  Missing Authorizations: The user does not have the necessary authorizations assigned in their user profile to access the specified DataSource.
  Role Configuration: The roles assigned to the user may not include the necessary authorizations for the specific DataSource.
  DataSource-Specific Restrictions: There may be specific restrictions or settings on the DataSource that limit access to certain users or roles.
  
  Solution:
  
  
  Check User Authorizations:
  
  Use transaction code SU53 immediately after encountering the error to see which authorization checks failed. This will provide insight into what specific authorizations are missing.
  Review the user’s roles and authorizations in transaction SU01 (User Maintenance) or PFCG (Role Maintenance).
  
  
  
  Assign Necessary Roles:
  
  If the user lacks the required roles, work with your SAP security team to assign the appropriate roles that include access to the DataSource in question.
  Ensure that the roles contain the necessary authorization objects related to the DataSource.
  
  
  
  Modify Role Authorizations:
  
  If the roles are already assigned but do not include the necessary authorizations, you may need to modify the roles in transaction PFCG to include the required authorization objects.
  Common authorization objects for DataSources include S_BW_AUTH (for BW authorizations) and S_DATASET (for dataset access).
  
  
  
  Testing:
  
  After making changes to roles or authorizations, have the user log out and log back in to ensure that the new authorizations take effect.
  Test the action again to confirm that the error has been resolved.
  
  
  
  Related Information:
  
  Authorization Objects: Familiarize yourself with the relevant authorization objects that control access to DataSources in SAP BW.
  SAP Notes: Check SAP Notes for any known issues or additional guidance related to authorization errors in your specific SAP version.
  Documentation: Review SAP documentation on user roles and authorizations to understand how to properly configure access for users.
  
  If the issue persists after following these steps, it may be necessary to consult with your SAP Basis or security team for further investigation.
